IMPROVEMENT IN CORSET-CLASPS AND.SPR|NGS.

The Schedule referred to in these Letters Fatent and making part of thesame.

Beit known that I, PETER H. NILES, of the city of Boston, county ofSuffolk and State of Massachusetts, have invented a new and usefulImprovement', in Corset-Olasps and Springs; and I do hereby declaredeclare that the following is a full and exact description thereof,reference being had to the accompanying drawing and to the letters ofreference marked thereon.

To enable others'skillc-d in the art to make and use my invention, Iwill proceed to describe its construction and operation.

Upon-the accompanying drawing- Figure 1, A, is an elevation of acorset-spring (right) having a local graduated corrugation, a. It isprovided with spring-clasps b b b, which are attached to and form partof said corset-springs. The corrugations a are enlarged at the center,laterally, and are also deeper at the center, longitudinally, taperinggraduallyto the-ends; this strengthens the corset-spring at the exactspot where a stay is required, for corrugations at the end do notaccomplish this purpose, having no eect, as they do not come where thestrain is received.

Figure 1, B, is an elevation of a corset-spring (left) having a localgraduated corrugation, and is provided with buttons c c c;

Figure 2 is an elevation of a pair of corset-springs (corrugated)connected by the spring-clasps b b b, and showing the buttons c c cretained in the angle of the `ktwoway slots by the spring of the clasps.

angled slots e; said clasps are located at suitable points along thespring A, and at corresponding points` on spring B are the projectingstuds C, which have enlarged heads which enter orifices d dsimnitaneously, and the spring is then moved in either directionvertically if the studs Center thc upper orifices, and laterally if theyentertbe lower orifices, until said studs are in the angle of slots e,where they are firmly held, the clasps forming double-acting springswith sutlicient strength to prevent them from detaching themselves, afault common to many corset-clasps.

The clasps are detached by reversing the clasping operation, that ismoving the studs C- simultaneously into either of the orices (l ll.

The corset-spring of `W'allace Fowler'diers from mine in the fact thatit has corrugations at the ends of the spring, which corrugations areofthe saine depth to their whole extent, which form does not acieomplish the purpose of my corrngation, it comes upon that part of' thespring which docs not require a back stay, while my spring has acorrugation deeper and broader in the center, gradually diminishing inwidth and depth each way, said corrugation being located at thecenterofthe spring where the'mziststrength is needed.
